务器端基于select I/O模型。为防止程序界面阻塞，有一个子线程用于不断接收socket并select其中的处理。客户端只有一个线程函数，不过其利用率很高，可用于远程目录交换，请求文件大小，创建若干线程来下载文件。文件传输有上传和下载,还有对等传输，这个项目中，传输文件具体指下载。 (side is based on the Treasury select I/O model. To prevent the program interface obstruction, a son threaded socket for receiving continuous and select which of treatment. Only one client thread function, but its high efficiency, long-distance directory can be used to exchange documents requested size, creating a number of threads to download files. Upload a file transfer and downloading, and the transmission of the project, specifically referring to transfer files downloaded.)

运用网络编码技术改进的无线路由协议，可以实现做大的吞吐量，实现节能功能(Using network coding technique to improve wireless routing protocol, can achieve big throughput, achieve energy saving function)

使用vc中的socket类实现的UDP通信程序源码(Using multi-threaded approach to achieve the source code of the UDP traffic)

实现window到linux的网络时间的计算(Implementation of window to Linux network time calculation)

wsk是win7上取代tdi驱动进行网络编程的技术，程序对wsk的接口进行封装，可以像应用层一样进行socket编程。(wsk is substituted on win7 tdi driven network programming techniques, procedures for wsk interface package, socket programming can be the same as the application layer.)

说明：  TCP简单客户端程序,使用socket套接字(TCP client,use socket)
